Use the following information to complete steps (a) through (d) below.

A random sample of n 1 equals 125

n1=125 individuals results in x 1 equals 40

x1=40 successes. An independent sample of n 2 equals 150

n2=150 individuals results in x 2 equals 60

x2=60 successes. Does this represent sufficient evidence to conclude that p 1 less than p 2

p1

=0.01 level ofsignificance?

(a) What type of test should beused?

A.

A hypothesis test regarding the difference between two population proportions from independent samples.

Your answer is correct.

B.

A hypothesis test regarding two population standard deviations.

C.

A hypothesis test regarding the difference of two means using amatched-pairs design.

D.

A hypothesis test regarding the difference between two population proportions from dependent samples.

(b) Determine the null and alternative hypotheses. Choose the correct answer below.

A.

Upper H 0 : p 1 greater than p 2

H0:p1>p2; Upper H 1 : p 1 less than p 2

H1:p1

B.

Upper H 0 : p 1 equals p 2

H0:p1=p2; Upper H 1 : p 1 greater than p 2

H1:p1>p2

C.

Upper H 0 : p 1 equals p 2

H0:p1=p2; Upper H 1 : p 1 less than p 2

H1:p1

Your answer is correct.

D.

Upper H 0 : p 1 equals p 2

H0:p1=p2; Upper H 1 : p 1 not equals p 2

H1:p1p2

(c) Use technology to calculate theP-value.
